A sexual act in which you mix semen and breast milk in an anus then suck the contents out with a straw. The feces already in the anus mix with the semen and breast milk to make a rusty brown color, similar to an old chamber pot. Ideally this would be mixed inside a pregnant woman's rectum, she would also provide the breast milk. The chamber pot should not be confused with shrimp boat, even though the two are very similar.
